Benefits of technology

This patent describes a method for distributing packet processing across several managed non-edge switching elements in a network. If there is a packet that the managed edge switching element cannot process, it can forward the packet to one of the managed non-edge switching elements for further processing. The method uses a hash function to determine which non-edge switching element to forward the packet to. This allows for efficient distribution of packet processing and improved network performance.

Problems solved by technology

The managed edge switching element may not be able to process the packet for different reasons.

Embodiment Construction

[0057]In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are set forth and described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention may be practiced without some of the specific details and examples discussed.

I. Environment

[0058]The following section will describe the environment in which some embodiments of the inventions are implements. In the present application, switching elements and machines may be referred to as network elements. In addition, a network that is managed by one or more network controllers may be referred to as a managed network in the present application. In some embodiments, the managed network includes only managed switching elements (e.g., switching elements that are controlled by one or more network controllers) while, in other embodiments, the managed network includes managed switching ele...

Abstract

Some embodiments provide a method that processes network data through a network. The method receives a packet destined for a network host associated with a logical datapath set implemented by a set of managed edge switching elements and a set of managed non-edge switching elements in the network. The method determines whether the packet is a known packet. When the packet is a known packet, the method forwards the packet to a managed switching element in the set of managed edge switching elements for forwarding to the network host. When the packet is not a known packet, the method forwards the packet to a managed switching element in the set of managed non-edge switching elements for further processing.
